Victorian Flora Biodiversity Records Summarized on a 10-Minute Grid

The Victorian Biodiversity Atlas flora dataset provides a spatial summary of plant species records across Victoria, Australia. It aggregates records onto a standard 10-minute longitude/latitude grid, counting occurrences and summarizing the first and last observation dates per taxon per cell. The dataset is published by the Department of Energy, Environment and Climate Action and was last updated in April 2026.

Use Cases

• Mapping species richness and distribution patterns based on aggregated record counts per grid cell.
• Analyzing temporal trends in species observations based on the summarized first and last record dates.
• Conducting regional conservation planning and gap analysis using the standardized 10-minute grid.
• Comparing biodiversity data across scales using related 5-minute and 1-minute grid summaries mentioned in the description.

Strengths

• Data is aggregated on a standardized 10-minute longitude/latitude grid (GDA94) for consistent spatial analysis.
• Records with spatial accuracy worse than +/- 9 km are excluded, which likely improves locational reliability.
• Summarizes temporal range with first and last observation dates per taxon per cell.
• Available under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The description does not specify the total time range covered by the summarized first and last dates.
